Optical components have a material-distribution gradient due to nanometer-size particles embedded in a solid matrix. The components are manufactured by forming a dispersion of nanometer-size particles in a liquid, curable matrix material, causing the particles to migrate in the matrix material on th ...

A process is disclosed for the production of compounds based on hydrolyzable silanes containing epoxy groups. The process involves adding one of the following substances to a pre-hydrolyzed silicon compound A with at least one hydrolytically non-separable group which includes an epoxy ring:

A photochromic coating composition contains a silicon-containing precondensate derived from a hydrolysable silane containing a polymerizable functional group on a hydrolysis-stable radical, a photochromic dye, a stabilizer, and nanoscale particles. The coating composition, when applied to transparen ...

A composite material is described which is characterized by a substrate based on vegetable materials, in particular vegetable fibers, vegetable fiber raw materials or vegetable fiber semifinished products, and by a nanocomposite which is in functional contact with said substrate and is obtainable by ...

Described is the use of nanoscale metal oxide particles as catalysts for the thermal and/or photochemical polymerization of species having at least one polymerizable carbon-carbon multiple bond and/or at least one carbon containing ring capable of undergoing a ring opening polymerization.

The invention relates to a nanocomposite for thermal insulation especially for fireproofing purposes, which can be obtained by combining (A) at least 35 wt. % of nanoscaled, optionally surface-modified particles of an inorganic compound; (B) 10-60 wt. % of a compound with at least two functional gro ...
